What the calculation assumes
We assume a reference output of 1,600–1,800 kWh per kWp per year for the Costa del Sol, a roof without significant shading and a typical day/night consumption split.
- Flat coastal roofs: ballasted mounting, no drilling
- Arabic clay tiles inland and in the Axarquía: dedicated hooks
- Shading from palms, lift shafts or neighbouring buildings: corrected in the real survey
